newbie here.
have ruby/sequel/sqlite and windows 2003 server working smooth.
but have problem with mysql
“gem install mysql”
run a basic ruby test script, got error popop
“this application has failed to start because LIBMYSQL.dll was not
found. Re-installing the application may fix the problem.”
Then copy LIBMYSQL.dll from my sql/bin to ruby/bin
this fixed the problem. Basic ruby / sql connection passed.
Then try to use sequel model with my sql code as following,
DB = Sequel.mysql(db_name, db_user, db_password, db_host, db_port)
class Test < Sequel::Model(:test)
end
tt = DB[“test”].filter(:key => ‘key’).first
got error:

connection looks ok but error on the filter().first same code works
for sqlite.
Any idea?
Appreciate.
